10 Claims.

This invention relates to an improvement in heaters, and particularly tothat type of apparatus designed for vehicular installation.

It is an object of the invention to provide a heater which isdirectional in its radiation, and which can be easily manipulated 'tochange the path of travel of the radiated heat.

Another object is that of providing a heater in which the output, ofradiated heat may be controlled in order to raise or lower thetemperature of the surrounding air.

' A still further object is that of providing an apparatus of thischaracter which is relatively rugged and simple in construction, andwill op- 5 erate over long periods of time with freedom from mechanicaldifficulties.

With these and other objects in mind, reference is had to'theaccompanying drawings, in which:- I

Fig. 1 is a front view of a heater embodying certain aspects of theinvention;

Fig. 2 is a side elevation of said heater partially broken away alongthe lines 2-2 and in the direction of the arrows as indicated in Fig. 1;

Fig. 3 is a sectional plan view of the heater taken along the lines 3-3and in the direction of the arrows as also indicated in Fig. 1; and

Fig. 4 shows a modified form of actuating member for the heat deflectingvanes.

In the several views, the heater shell or body cover is shown at l0positioned over a conventional heater core and head assembly I I.Ornamental strips l2 are formed with rivet pins I3, which are passedthrough openings in the shell and thereafter flattened or headed as atM, thus holding the parts in position. Shell I0 is provided on its frontface with bearing portions l5, in which shafts l6 are rotatably mounted.These shafts, in turn, have manipulating knobs H at the outer endsthereof, and pinion gears l8 mounted on their inner ends; these gearsbeing held in position as, for example, by means of screws Hi. In thisconnection, it will be noted in Fig. 1 that the lower ends of the shaftsI6 are preferably squared so that the gears l8 are positively engagedwithout any danger of slippage. Interposed between the adjacent faces ofthe knobs and the shell are gaskets or washers 20, which may be made offelt, leather, or other Y suitable material.

Adjacent the gears I8 and cooperating therewith is a ring gear 2| whichis provided with a rearwardly extending flange portion 22. A ring shapedplate 23 is coupled to this flange by rivets 24 or equivalent fasteningmeans, this 1935, Serial No. 36,06!

plate having an outwardly and rearwardly extending flange 25 which bearsagainst the shell l0 adjacent the bearing members l5. Upon manipulationof either of the knobs l1 the ring gear and the attached plate are freeto rotate, and the latter may be turned so as to assume any positionthat may be desired.

Carried by the plate are a series of heat deflecting vanes 26 which areshaped to conform to the circular opening of such plate. These vanes areeach provided with handle portions 21' which may be formedintegrallytherewith or secured thereto by means of rivets 28, as shownin Fig. 3. Each of the vanes may have one of its ends providing a pivotpin 29 which rotates within an opening 30 in the plate 23. At theopposite end of each vane a pivot pin 3| is 'slidably carried in bearingportions 32 and 33 and is encircled by a coil spring 34 which, incooperation with the bearing portion 32 and the shoulder forming a partof the pin, tends to force the latter into position in the opening 36formed in'the plate 23. The rear end of the bearing pin is distorted asat 31 or otherwise secured to prevent an accidental displacement of thepin when the parts are disassembled.

In assembling the apparatus each of the deflecting vanes is mounted uponthe plate by placing the bearing pin 31 thereof in the opening 36 andthen moving the entire vane in the direction of the opening 36 so as tocompress the spring 34 and move the bearing pin inwardly. The bearingpin 29 can thereupon be inserted in the opening 30 and the vane allowedto move in the direction of the opening 30 under the urging of thespring 34. In addition to providing a ready means of assembly, thespring provides a sufficient tension on each of the vanes so that theymay be maintained in any desired position.

In operation, all or any of the deflecting vanes are-moved about theirrespective points of pivot to assume predetermined positions, as, forexample, shown in Fig. 2. Thereafter, the manipulating knob or knobs areturned to rotate the 45 plate so that the air blown through the core bymeans of the fan will be deflected to either side of a planeintersecting the heater and any desired portion of the vehicle interior.To overcome any tendency towards looseness or rattling, the plate 23 maybe provided, as shown in Fig. 2, with a suitable number of spacedsockets 38, each of which receive a coil spring 39 and a ball 40, Thelatter under pressure from the springs bear against the surface of theshell l0 and prefin ' 6 alternative form 10 tending flange 44 and ventrattling of the parts, although allowing the cover plate to rotatefreely with respect to the frame.

Referring now to Fig. 4, there is shown an cover plate. In this case twofriction disks ti are carried by the shaft or shafts 42 and which extendto either side of a friction ring 43. This ring is likewise providedwith an inwardly exis secured to the plate E5 y rivets 46,]or' othersuitable means. A coilspring #31 bears against the lower surface of theinner friction disk, thus clamping the friction ring under pressurebetween the two, friction disks. The spring is held in position by meansof, for example, a screw48. In operation, the turning of themanipulating knob'49 effects a turning of the friction disks 48, which,in turn, carry with them the friction ring 43, resulting in a rotationof the plate. discussed modification, a washer 50 is placed between theknob and the ornamental strips.

It is apparent that while two manipulating knobs are disclosed in allforms of the apparatus, it will be understood that theshroud is coupledin any desired manner with the head and core assembly. The shell andparts hereto"- fore described are assembled, and thereafter they aretelescoped over the core assembly and attachedin any desired mannerthereto. It is also apparent that the same general results could beobtained by omitting one of the manipulating knobs and its dependentgear from the assembly. Thus, among others, the several objects of theinvention, as specifically aforenoted, are

achieved. It will be understood that numerous heater.
